Electronics automotive Express in-vehicle networking PCI PCIe semiconductorDIODES INC. Series of automotive-compliant PCI Express (PCIe) 3.0 technology packet switches for next-generation, in-vehicle networking applications utilizes an architecture that enables flexible port configuration with upstream, downstream and cross-domain end-point (CDEP) ports being assigned according to requirements. The PI7C9X3G606GPQ offers 6-port/6-lane operation, the PI7C9X3G808GPQ 8-port/8-lane, and the PI7C9X3G816GPQ 8-port/16-lane. Devices are targeted at ADAS, telematics, infotainment systems, and controllers that are utilized as zonal networking architectures continue to emerge. Device’s elevated signal integrity performance supports long trace lengths, with losses of <30dB. They can connect with up to seven different endpoints and support multi-host applications. Each switch features a built-in low-power clock buffer, thereby simplifying designs, saving space, and reducing the associated component count. Their typical latency is only 150ns.
